/**
 * <p>Declares a method as a controller. If declared at the type level,
 * it applies to all methods in the type.</p>
 *
 * <p>A controller method that returns void is required to be annotated with
 * {@link javax.mvc.annotation.View}. A controller method can return a view path
 * as a {@link java.lang.String} or as part of a {@link javax.mvc.Viewable} or a
 * {@link javax.ws.rs.core.Response}. If a controller returns {@code null} and it is
 * annotated with {@link javax.mvc.annotation.View}, then the value of this
 * annotation is used as a default. If a controller method returns a
 * different Java type, its {@code toString} is called and the result
 * interpreted as a view path.</p>
 *
 * <p>Example:
 * <pre><code>
 *     &#64;Controller
 *     public String sayHello() {
 *         return "hello.jsp";
 *     }
 * </code></pre>
